I would expect libxml2 v2.7.8 to result in libxml2.2.dylib having a "compatibility version" of 10.0.0 and a 
"current version" of 10.8.0. A version in the 9.x.y range is indicative of libxml2 v2.6.x. What the error is 
saying is that the version of libphp5.so that is being loaded was compiled against libxml2 v2.7.x but the 
version of libxml2.2.dylib that is being found at runtime is from libxml2 v2.6.x. If you are on an older 
version of OS X (e.g., pre-10.6) then the error suggests that the system version of libxml2.2.dylib is being 
loaded rather than your locally built copy.  If you're on OS X 10.6 or newer then it's hard to guess where 
the old copy of libxml2.2.dylib is coming from.

Hope this helps,
